ABB 768301 PROEB 2 Gas Sampling Probe 1200 mm for Gas Analyzer Systems

ABB 768301 Product Overview

The ABB 768301 PROEB 2 is a gas sampling probe associated with industrial gas
analyzer equipment. Unlike an analyzer itself, the probe belongs to the sampling
section of the measurement system. Its purpose is to establish a controlled path
for collecting process gas from the selected measurement location.

Industrial gas analysis systems are commonly used where process conditions need to
be monitored continuously or at defined intervals. Depending on the application,
the analyzer may measure gas composition, concentration, oxygen content, combustion
characteristics, emissions-related parameters, or other process variables.

Before a gas reaches the analytical measuring section, the sampling system must
obtain gas from an appropriate point in the process. The sampling probe is therefore
an important mechanical component of the overall arrangement. Its installation
location, length, process connection, sampling path, and compatibility with the
surrounding system all need to correspond to the intended analyzer installation.

PROEB 2 Configuration

The PROEB 2 designation is associated with the ABB 768301 part reference. Available
product identification information describes this component as a gas sampling
element with a 1200 mm length. The combination of part number, PROEB 2 designation,
and physical length provides useful information for distinguishing the component
from other sampling arrangements.

Gas sampling probes are not interchangeable solely because they perform the same
general function. Differences in length, process connection, construction,
installation position, temperature conditions, and sampling requirements can affect
whether a particular probe is appropriate for a specific analyzer system.

For this reason, ABB 768301 should be identified using the complete part number
whenever it is referenced in equipment documentation, spare-parts records,
maintenance databases, or analyzer-system component lists.

1200 mm Sampling Length

One of the most useful identification characteristics of ABB 768301 is its
1200 mm length. The physical length of a gas sampling probe can be important in
applications where the analyzer sampling point is positioned at a specific
distance from the process connection or where the probe must extend into a
designated sampling area.

Probe length can also affect the mechanical arrangement of the sampling system.
A longer probe may be required when the process connection is separated from the
desired sampling position, while the correct insertion depth can help locate the
sampling point within the intended process region.

When replacing or identifying a probe, the 1200 mm dimension should therefore be
compared with the original system documentation and installation configuration.
Matching the part number alone is useful, but confirming the physical arrangement
provides an additional layer of identification accuracy.

Gas Sampling System Function

A gas analyzer system normally consists of several interconnected stages. Process
gas is first collected from a selected location, after which the sample may pass
through additional components before reaching the analytical measuring section.
Depending on the installation, these stages can include sample conditioning,
filtration, temperature control, moisture management, flow regulation, and
transport lines.

The sampling probe provides the initial interface for obtaining the gas. Its
position can therefore have a direct relationship with sample representativeness.
If the probe is installed at an unsuitable location, the collected gas may not
accurately represent the process condition that the analyzer is intended to
measure.

Correct mechanical installation is consequently an important part of analyzer
system design. The probe must be positioned according to the process engineering
requirements and the specific sampling arrangement associated with the analyzer.

Technical Specifications

Process Gas Sampling

The quality of an analytical measurement depends on more than the analyzer
electronics alone. The sample must reach the analyzer in a condition that remains
representative of the process. The sampling probe is therefore an essential part
of the measurement chain.

In industrial installations, process gases can contain dust, moisture, corrosive
components, high-temperature constituents, or other substances that require
appropriate sample-system design. The probe and associated components must be
selected with consideration for the actual process environment.

The ABB 768301 is therefore best understood as part of a complete sampling
architecture rather than as an independent measuring instrument. Its function
begins at the process sampling location and connects the physical sampling point
with the subsequent stages of the gas-analysis system.

Integration with Gas Analyzer Equipment

When integrated into a gas analyzer installation, the sampling probe works together
with downstream sample-handling components. The overall system may be designed to
transport the collected gas through tubing or other connections before it reaches
the analyzer.

The complete arrangement must maintain an appropriate sample flow and protect the
analytical system from unsuitable process conditions. Depending on the process,
sample conditioning can be required before measurement. The design of these
downstream stages is application-specific and should be matched to the analyzer
and the gas being measured.

Because ABB 768301 is a physical sampling component, its correct installation
requires attention to mechanical fit, probe position, sampling depth, process
connection, and compatibility with the associated ABB analyzer system.

Industrial Applications

Gas sampling components are used across a broad range of industrial processes
where gas composition or process-gas characteristics need to be monitored.
Applications can include combustion systems, process plants, emission-monitoring
installations, chemical processing, energy production, and other industrial
environments using continuous or periodic gas analysis.

The actual application of ABB 768301 depends on the analyzer system and the
corresponding process sampling arrangement. The probe should therefore be
considered together with the complete analyzer configuration rather than selected
solely according to its general gas-sampling function.

The 1200 mm length is particularly relevant when the installation requires a
defined insertion or sampling distance. Matching the probe’s physical dimensions
to the process connection and sampling location helps maintain the intended
mechanical arrangement of the system.

Product Identification

Accurate identification of ABB 768301 is important when maintaining gas analyzer
systems. The part number should be recorded together with the PROEB 2 designation
and 1200 mm length where these details are available in the equipment records.

Searching only for a generic description such as “gas sampling probe” can produce
multiple components with similar functions. Using the exact ABB 768301 reference
provides a much more specific identification path and helps distinguish the
component from other probe configurations.

For engineering documentation, the recommended product reference is therefore
ABB 768301 PROEB 2 Gas Sampling Probe, 1200 mm. This wording combines the
manufacturer, part number, configuration, component function, and principal
dimensional characteristic.

Selection Considerations

Before incorporating ABB 768301 into an existing gas analyzer system, the complete
installation should be reviewed. Important considerations include the analyzer
model, process sampling location, required insertion length, process conditions,
connection arrangement, sample transport path, and associated conditioning
equipment.

The 1200 mm length should be verified against the physical installation. A probe
with an incorrect length may change the sampling position or prevent the component
from fitting the intended process connection. The PROEB 2 configuration should
likewise be matched to the corresponding system documentation.

These checks are especially important in analytical systems where the sampling
arrangement is engineered as a complete system. A mechanically compatible component
is not necessarily appropriate unless its configuration corresponds to the intended
analyzer and process installation.

Conclusion

ABB 768301 is a PROEB 2 gas sampling component associated with industrial gas
analyzer systems. Available product identification information specifies a
1200 mm length, making the part number and physical dimension important references
when identifying the component.

As part of a gas analysis installation, the sampling probe provides the physical
interface through which process gas enters the sampling arrangement. Its position,
length, and integration with downstream sample-handling components contribute to
the overall sampling architecture.

The ABB 768301 PROEB 2 should therefore be identified by its complete part number
and configuration when documenting an analyzer system. For replacement or system
integration purposes, the associated analyzer model, process connection, sampling
location, 1200 mm length, and complete sample-system design should be considered
together to ensure the correct component configuration.
